★ Top Answer
The Ford Transit Van might trigger a P1103 trouble code if the onboard diagnostic system detects an abnormal and elevated voltage from the MAF, or mass air flow sensor. The Transit's PCM receives information from the MAF, and the P1103 signifies that the sensor is sending voltage readings that are acceptable but higher than the usual range. Common causes of this code can include faulty wiring harnesses, loose electrical connections, or dirty, blocked, or damaged sensors. In addition, there could be a vacuum leak present in the emissions system. If your vehicle scans for this code, you may have already noticed a decrease in fuel efficiency, acceleration capability, and instances of stalling while idling. The cost to replace the MAF sensor typically falls between $170 and $220 in parts and labor.

The powertrain control module (PCM) will set a P1103 fault code when the voltage signal from the mass air flow (MAF) sensor is elevated beyond the standard range, yet remains within the limits set by the manufacturer.
